Well, i`ll see if i can help you, because mine is running flawlessly since two years.
It works fine with the standard march rom, as well as the hybrid rom. I recomend using the GSM c19 module with it, as that gives me the best audio and signal quality.
The standard one however gives MUCH better battery life, 2-4 days on the slim and 5-7 days on the extended battery, depending on usage. But it also requires some tweaks to make it run smoothly:
In power options, disable "Device goes to sleep after..." as soon as possible, that`s what causes a lot of freezes. And if you have the phone open you don`t really need it to sleep anyway, it does that when you close it, i think so anyway
Disable FreeMem options to close applications automatically. That also seems to be a major source for lockups. Only enable the option to transfer temporary files to resident flash, that works fine for me. Sure, you will use much more memory as all the apps are only minimised and not closed, but i use another program (SBP Pocket Plus) to handle this problem.
To preserve RAM, you`ll have to install all additional applications either to resident flash or the SD card, to do that you`ll need to modify some registry settings.
Go to HKEY_LOCAL_MACHINE\Software\Apps\Microsoft Application Installer and set all the values to 1, except nDynamicDelete, set this to 0.
Now whenever you run a .cab file for installation, you will be asked for the path it should be installed in.
So much for the base setup, now everything should run smoothly and without lokups, if it does not, maybe it`s a hardware related issue with your device.
Some applications i can recomend for the MPx:
SBP Pocket Plus; gives you tons of extra features in internet explorer, file explorer, and many other apps, too much to write it all up here, check it out on google to see all its features if you like. It`s payware, but really worth it i think, enhances the device a lot!
OxiosMemory (freeware)
Can close applications that have not been closed properly, whenever you are very low on RAM, run this and it`ll clear it with no hassles.
ClearTemp (also freeware)
Removes ANY garbage you may have left on your phone such as temporary files from explorer, installer, dead registry entries and all such. Small program but extremely useful!
I hope i could help some of you here
